The demand for HDDs has increased significantly due to Chia cryptocurrency mining in recent times causing major shortages and increasing retail prices. Seagate and Western Digital are increasing the production of their high-capacity HDD models by increasing the utilization rate on existing production lines in an attempt to satisfy this demand. The companies have limited options to increase production in the short-term due to bulk contracts for 60% - 70% of total production and neither company plans to construct new factories in the immediate future. The total global storage capacity allocated to Chia mining has recently surpassed 20 Exabytes up from 1 Exabyte in April and doesn't show any signs of stopping. The shortages look set to continue with both companies happy to monitor the situation and take advantage of the increased demand before deciding on future expansion plans in the coming years.
